Abstract
The invention provides high-stiffness composite packaging paper and a preparation method thereof, and belongs to the field of packaging paper. Aiming at the defects that a net structure of a mineral fiber in stone paper machining is difficult to sufficiently retain, so that the stiffness of the stone paper when being used as the packaging paper is low in the prior art, formation of barium sulfate is utilized to enable the barium sulfate to wrap the mineral fiber, the mineral fiber can roll and slide more easily when being processed in an extruding machine due to the spherical characteristic of the barium sulfate, so that the dispersion of the mineral fiber is promoted, the damage to the fiber is avoided, the mineral fiber can form the net structure in the paper and the aim of improving the stiffness of the paper is realized. Meanwhile, through wrapping the mineral fiber by the barium sulfate to reduce the using amount of a lubricant, the defect that the paper is softened due to the fact that a large amount of lubricant is used is overcome. Further, net grains form on the paper during a hot tensile process, through soaking a stiffness-increasing sizing agent, the sizing agent fills the net grains and forms sizing agent layers at the upper and lower surfaces of the paper, and finally the high-stiffness composite packaging paper which is suitable for making various packaging cartons and paper bags is obtained.
Description
Technical field
The present invention relates to the packaging vessel package paper fields such as tr, box, bag, particularly relating to a kind of take mineral fibre as high-stiffness composite packaging paper of main raw material and preparation method thereof.
Background technology
Along with paper is in the extensive application in the fields such as packaging, demand is increasing.Particularly ivory board comprises a large amount of application ivory board of the food product pack such as medicine, healthcare products, makeup, electronic product, handbag, clothes box, jack-in-a-box, cigarette pack, dixie cup, instant noodle box, hamburger box, cake box in the application of packaging field, causes the sharp increase of ivory board demand.Current ecommerce, logistics fast development, promoted the rush of demand of the wrapping paper such as carton, carton product further.
Due to the production drawback of traditional pulp based paper and the resource contradiction of wood pulp paper using, make it can not meet the Packaging Industry huge with demand of a great variety, more can not meet the needs of social sustainable development.Particularly conventional paper, in order to the demand of satisfied packaging, needs further surface coating process, increases the cost of wrapping paper at present.
The composite base paper being main raw material with mineral substance inorganic powder provides a feasible approach, as synthetic paper, stone paper for developing green packing articles substitutes traditional packing articles.
Chinese invention patent CN102225576A discloses a kind of full-automatic stone papermaking production process.Plastics PP or PE of the stone powder after modification and ratio 15%-20% or PHBV and auxiliary agent mix and blend are sent into tablets press by banburying twin-screw extrusion by this production technique, gluey liquid extruding will be made to wide film head extrusion sheet again through banburying device singe screw high speed rotating, obtain stone paper through three-roller calendaring; China Patent Publication No. CN1378909A proposes a kind of environment protecting paper, by the inorganic mineral powder of 56-80% and the polyvinyl resin of 43-18% and auxiliary agent by extruder grain, obtains stone paper at O pattern mouth by blowing; China Patent Publication No. CN1202166C discloses by calcium carbonate superfine powder after coupling agent surface treatment, delivers to the manufacture method that flattener prolongs molded stone paper successively with after static inhibitor, tinting material, lubricant and polyolefin resin mixing extrusion; China Patent Publication No. CN101462387A discloses ultrafine inorganic powder is melt extruded the method obtaining paper grade (stock) pellet after Aluminate coupling processing with high density polyethylene(HDPE).Be that the stone paper of processing main body has broken away from dependence to paper pulp with inorganic powder, production process no longer produces contaminated wastewater environment.
Because stone paper is formed by thermoplastic fabrication equipment's screw extruding, calendering formation, thus lacking the support of fiber, showing as well-pressed degree when stone paper is for making carton, carton, paper bag low.Use part mineral fibre can improve the deflection of stone paper for the preparation of stone paper, but because stone is flowed by thermoplastic to process, the reticulated structure of mineral fibre is difficult to abundant reservation, thus make mineral fibre in stone paper, be difficult to play the mesh-supported of fiber, thus cause stone paper for there is well-pressed degree low defect during wrapping paper.
Summary of the invention
In order to overcome above-mentioned defect, the object of the present invention is to provide a kind of high-stiffness composite packaging paper, it is characterized in that composite packaging paper contains by the coated mineral fibre of barium sulfate, composite packaging paper surface impregnation Hardening sizing agent.By barium sulfate coated mineral fiber, mineral fibre is made to add man-hour fibre-tendering and reduce extruding, and dispersed formation network structure, particularly by surface impregnation sizing agent, final acquisition high-stiffness composite packaging paper, is applicable to make all kinds of packing carton, paper bag.The preparation method of this composite packaging paper is provided further.
A preparation method for high-stiffness composite packaging paper, it is characterized in that composite packaging paper contains by the coated mineral fibre of barium sulfate, composite packaging paper surface impregnation Hardening sizing agent, operates as follows:
(1) by water-soluble for the sodium sulfate of 8-10 weight part, be mixed with the solution that mass concentration is 25-30%, the mineral fibre of 25-35 weight part is dispersed in metabisulfite solution, slurry is formed with the stirring velocity of 1500-2500rpm dispersion 5-15min, then add sulfuric acid and slurry pH is adjusted to 3-5, and the barium carbonate of 10-15 weight part is slowly added, the process white formed gradually is evenly coated on mineral fiber surfaces, is then filtered dry for subsequent use;
(2) mineral fibre coated by process white step (1) obtained and the talcum powder of 20-30 weight part, the kaolin of 10-15 weight part, the lubricating auxiliary agent of 1-2 weight part, the high molecular polymer of 10-15 weight part stir 20-25 minute in mixing machine high speed, and mixing temperature is 100-120 DEG C;
